Can I prepare a ground beef casserole ahead of time?

Yes, you can assemble the casserole ahead of time, cover it tightly, and refrigerate it for up to 24 hours. Add a few minutes to the baking time when cooking from cold.

What can I add to ground beef casserole for more flavor?

Consider adding Worcestershire sauce, a dash of hot sauce, different herbs and spices like garlic powder, onion powder, smoked paprika, or Italian seasoning, or even a can of diced tomatoes with green chilies for extra flavor.

What sides go well with ground beef casserole?

Great side dishes include a fresh green salad, steamed vegetables (like broccoli or green beans), garlic bread, or a simple coleslaw.

How do I keep my ground beef casserole from being watery?

Ensure you drain the excess grease from the cooked ground beef. You can also thicken the sauce with a cornstarch slurry (cornstarch mixed with cold water) before baking. Avoid adding too many watery vegetables.

Can I freeze ground beef casserole?

Yes, you can freeze it either before or after baking. Wrap it tightly in plastic wrap and then aluminum foil, or store it in an airtight container. It can be stored in the freezer for up to 3 months. Thaw completely before baking or reheating.

Instructions

Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
In a large skillet over medium-high heat, cook ground beef and onion until beef is browned and onion is soft, about 7-8 minutes. Drain excess grease. Add garlic and cook for 1 minute.
Add tomato sauce, cream of mushroom soup, beef broth, Worcestershire sauce, oregano, smoked paprika, salt, and pepper to the skillet. Stir to combine and bring to a gentle simmer.
Stir the uncooked pasta into the sauce mixture. Pour everything into the prepared baking dish. Cover tightly with aluminum foil.
Bake, covered, for 25 minutes.
Remove from oven and carefully remove foil. Sprinkle 1.5 cups of shredded cheddar cheese evenly over the top.
Return to the oven, uncovered, and bake for 8-10 more minutes, or until cheese is melted and bubbly.
Let the casserole rest for 5-10 minutes before serving. Garnish with remaining cheese and parsley if desired.

Notes

Letting the casserole rest before serving is crucial for a cleaner slice. For a from-scratch version, substitute the canned soup with a white sauce made from 2 tbsp butter, 2 tbsp flour, and 1 cup milk.
